Title: Compensated shunt type electric snap action device
Inventor: SIIBERG HEMMING G
IPC: H01H37/50
Filed: 1964-01-15
Abstract: 1,013,651. Thermal switches. TUNG-SOL ELECTRIC Inc. Jan. 15, 1964, No. 1835/64. Heading H2B. A snap-action switch comprises a resilient vane and two expansible pull means acting thereon in opposition. The switch comprises an insulating base 2 carrying terminals 4, 6, a frame 8 mounted on the base and in electrical contact with the terminal 4, a resilient vane 16 mounted on the frame by a screw 18, an expansible pull ribbon 44 connected at its ends to opposite edges of the vane (see Fig. 3), a contact 46 mounted on the ribbon, an expansible pull wire 26 which acts on the vane through an angle member 24; a resistor 32 connected between the wire 26 and terminal 6 and a bracket 34 carrying a fixed contact 42. When the contacts are open current passes from terminal 4 to terminal 6 via wire 26 and resistor 32, causing the wire to heat up and expand. Simultaneously the ribbon 44 cools and the contacts 42, 46 are thus caused to close. The wire 26 and resistor 32 are then shunted, the current passing, through the vane 16, ribbon 44, contacts 42, 46 and bracket 34. This causes the ribbon 44 to heat up and expand and the wire 26 to cool so that the contacts return to their open condition. The cycle is then repeated.

An electric train driven by single phase electric current through individual motors driving axles of a plurality of cars has one of the cars equipped with a trolley, main switch, transformer and other associated apparatus such as a variable resistance switch to vary the high tension voltage supplied to the cars of the train through a unipolar feeder 3 to which the motors are in turn connected through individual transformers. The high tension current of about 15,000 volts collected by the trolley car A passes through a winding 1 and a unipolar feeder 3 to respective transformer windings 2a, 2b, 2c, .... in trolley cars A, B, C, ... The feeder 3 is connected between the cars by electrically insulated resilient buffers 5 which are withdrawn to the inoperative position by air pressure. The trolley car A may drive the train from either end or any position intermediate thereof but must be provided with a control system operated from the front car to operate the variable resistance switch apparatus. A trolley car may be provided at each end of the train and then the train can be operated from either end without the necessity of a control system extending along the train.

Patent GB-1013885-A (GB)
Title: Olefine copolymers
Inventor: CLARK KEITH JASPER
IPC: C08F10/00
Filed: 1963-01-17
Abstract: A copolymer of 3-methyl-butene-1 containing between 20 and 90% by n-butene-1 monomer units is made by copolymerizing the monomers in the presence of a stereospecific catalyst under such conditions that the rate of polymerization of each monomer is substantially constant throughout the polymerization.  The copolymer has a predominant crystalline form or forms stable at room temperature. The copolymerization may be effected in a hydrocarbon diluent but is preferably effected in bulk, e.g. in the presence of excess 3-methylbutene the slower polymerizing monomer.  The catalyst may be preformed or formed in situ. The copolymer is recovered by conventional techniques e.g. addition of alcohol, e.g. isopropanol, and/or hydrochloric acid, and/or acetylacetone.  The n-butene is generally added portionwise.  The catalyst is an organometallic compound plus a transition metal compound, e.g. TiCl3 or TiCl4.  The organometallic compound is preferably an aluminium trialkyl or an aluminium alkyl chloride. The preferred transition metal compound is obtained by reducing TiCl4 with an aluminium dialkyl chloride at a temperature between - 20 DEG  C. and +20 DEG  C.  Transparent articles such as fibres, films, and bottles may be made from the copolymers by using known techniques.

Title: Controlled generation of magnetic bubble domains
IPC: G11C19/08
Filed: 1976-01-21
Abstract: 1526871 Magnetic bubble generators INTERNATIONAL BUSINESS MACHINES CORP 21 Jan 1976 [21 April 1975] 02323/76 Heading H3B Magnetic bubbles having desired wall states are produced by generating a bubble having a known wall state, elongating it, rotating its wall magnetization transversely and splitting it. In Fig. 3, currents I 2 , I 3  in conductors 12, 14 and an in plane field 23 nucleate a bubble 22a having a pair of Bloch lines B. Currents I 1  and -I 2  in conductors 16, 12 move the bubble to position 22b and allow the Bloch lines to take antiparallel positions owing to the gyromagnetic spaces in a moving domain wall. Current I, alone reduces the bias field and the bubble 22b elongates within the constriction in conductor 16. The application of an in-plane field H or a velocity component V to the elongated bubble 22c causes the wall magnetization vector to rotate to an orientation transverse to the wall, thereby establishing a further pair of Bloch lines when the bubble is split by a current pulse I 3  in. conductor 14. The further pair may be associated with either half of the elongated bubble by choice of direction of H c  or V either to produce bubbles D 1 , D 2  as in Fig. 2a designated state S= 1 and S = - 1 respectively, or two bubbles each having a single pair of Bloch lines designated state S=0. The process may be repeated using either of the generated bubbles as starting point and possibly recirculating one to produce any desired wall state bubble as outlined in Fig. 9 (not shown).

Title: An Analogue-To-Digital Converter
Inventor: SHUTTLEWORTH JOHN EDWARD
IPC: H03M1/00
Filed: 1967-01-17
Abstract: 1,154,795. A/D converters. SOLARTRON ELECTRONIC GROUP Ltd. 16 Jan., 1968 [17 Jan., 1967], No. 2486/67. Heading G4H. After an analogue to digital converter operated in discrete steps has digitized an analogue voltage to the nearest unit (e.g. as in Specification 950,647), a remainder voltage of less than one unit being indeterminate, a signal Vi, Fig. 1, the final value of which differs from the initial value by an amount which represents the remainder voltage, is fed to comparator 10, the output 3 from which controls a gate 12 through which a pulse is fed to a counter or integrator 11 (connected to the other input 2 of the comparator) whenever the comparator inputs differ by a predetermined amount. The stepped voltage V 0  fed to the comparator may be differentiated or passed through a blocking capacitor so that a pulse train representing the remainder voltage is obtained. Where the input Vi to the comparator may decrease as well as increase a current drain may be connected to one side of the integrator (Fig. 3, not shown). Alternatively separate comparators 30a, 30b (Fig. 5) may be used when the voltage is increasing or decreasing, AND gates 32a, 32b passing positive or negative pulses to the integrator 11 when their associated comparators deliver output signals 3a or 3b. By differentiating the integrator output signal V 0  positive and negative output pulses representing increasing and decreasing values of V i  may be obtained. In the embodiment of Fig. 6 (not shown) the output pulses from the gate (12) are accumulated positively in a reversible binary counter (21) controlling a D/A converter (22) the output signal V 0  from which is fed to the comparator. A clock pulse generator (24) counts the binary counter (21) downwards. The output pulses (VP) passing through the gate (12) represent the remainder voltage (Vi), the clock pulse generator (24) providing a zero offset to the converter. In a modification the comparator may be replaced by two comparators and two associated gates, the output from one of the gates counting the binary counter upwards and the output from the other counting it down.
